Once someones bought something from you on eBay, you suddenly have all sorts of details on them. In marketing terms, this information is gold dust. If someones bought from you once before, then the chances are that at some point in the future theyll want to buy a similar item, and you can take advantage of this to market to them directly.
The simplest form of direct marketing is the email newsletter and its one that is still oddly underused on eBay. Simply ask people who buy from you if theyd like to be added to your mailing list, and then send them a monthly update on your new items. You should also include some information you think might be useful to them, to give the email more value.
For example, heres a newsletter you might write if you were selling DVDs.
